We have an issue when we add a Windows 7 machine to our domain.
We have a domain, running a Windows Server 2003 domain, and using XP machines, and are wanting to start using Windows 7.
However, when we try and join a Win 7 machine to the domain, shortly afterwards (minutes), the Win7 machine crashes, and on reboot, it fails to recover using any System Restores (which means nothing in the Event Log!).
This has happened on reinstalled XP machines (wiped, and installed Win7 on them) and on new Win7 machines (machines built with, and supplied with Win7 installed)
There is a group policy on the network, but the user logging in is exempt from that (admin...)
Update: Appears to be unrelated to UAC
